zcjhwl opened a new issue #3083: Online problem for sharding-jdbc

   dependency>
           <groupId>org.apache.shardingsphere</groupId>
           <artifactId>sharding-jdbc-spring-boot-starter</artifactId>

   question
         Online problem, every time you restart the project, after a successful restart, a request will appear in the persistence layer for a short time, such as 20 seconds. It takes a long time to appear, and then it will return to normal. At that time, the QPS is stable and the database connection is sufficient.
   
   configuration
   - spring.shardingsphere.datasource.ds0.type = com.zaxxer.hikari.HikariDataSource
   - spring.shardingsphere.datasource.ds0.driver-class-name = com.mysql.jdbc.Driver
   - spring.shardingsphere.datasource.ds0.maximum-pool-size = 100
   - spring.shardingsphere.datasource.ds0.minimum-idle = 50
   - spring.shardingsphere.datasource.ds0.connection-init-sql = SET NAMES utf8mb4
